First off, if you dont plan on overclocking the cpu, it would be best not to go with the K model because thats the unlocked one and the one that you can overclock. To save a bit more of money consider going with a F mode which doesnt have an IGPU because you dont really need it with a dedicated gpu. For your price range i think a 13700F should be sufficient.
As for the GPU i think that for "basic 3d modeling" and 2d motion graphics a 4070ti should suffice. Anything higher than a 4070Ti would be overkill and anything less might not be enough to futureproof the pc.
A fast and reliable storage option would be the 980pro 2tb which has dropped significantly in price and is really fast.
I see that your pc part picker list is for a white pc build but if you didnt care about the color these are what i recommend
